…Using a high-speed camera, he analyzed work movements in units of 1/2000 of a minute. As a result, he abstracted 18 basic actions such as "search," "find," and "select," and gave them the name "therblig," which is the reverse of Gilbreath's spelling, and a unique symbolic notation. He tried to break down various work movements into these elements to determine the best way to work. … From [Work Study]...He conducted experimental scientific research on various tasks, including time studies, in the early 20th century, based on the idea that there must be an objective standard amount of work for a piecework wage system as a fair amount of work in a day. The Gilbreth couple, FB and LM Gilbreth, believed that there must be a single best way to perform a task, and developed the therblig (Gilbreth's name spelled backwards), a microscopic unit for analyzing human motion, and established the motion study method to find the best way to perform a task. For a long time, work studies have developed as motion and time studies, centered on the techniques of these two men. ... *Some of the terminology explanations that mention "therblig" are listed below.

…高速度カメラを用いて,1分の1/2000を単位に作業動作を分析した。その結果,彼は〈さがす〉〈見いだす〉〈選ぶ〉などの18の基本動作を抽象し,それらにギルブレスのつづりの逆であるサーブリッグtherbligという名称と,独特の記号表記を与えた。種々の作業動作をこれらの要素に分解して,最良の作業方法を定めようとした。… 【作業研究】より…彼は20世紀初めころ,出来高賃金制度の基準となる作業量が1日の公正な仕事量として客観的に存在するはずだという思想に立って,これを見いだすため,時間研究time studyをはじめとする各種作業への実験科学的研究を行った。ギルブレス夫妻F.B.& L.M.Gilbrethは,人が行う作業には必ず唯一最善の作業方法が存在するはずだという思想に立ち,人間の動作を分析する微細単位のサーブリッグtherblig(ギルブレスの逆綴りによる名称)を開発し,最善作業方法を求める動作研究法motion studyを確立した。作業研究は長い間この両者の技法を軸に,motion and time studyとして発展してきた。… ※「therblig」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
